CRUISE CONTROL OPERATIONS
The cruise control allows driving at a speed
between 25 to 89 MPH (40 to 144 km/h) without
keeping your foot on the accelerator pedal.
To turn on the cruise control, push the MAIN
switch on. The CRUISE indicator will come on.
To set cruising speed, accelerate your vehicle to
the desired speed, push the SET/COAST switch
and release it. (The CRUISE SET indicator will
come on in the instrument panel.) Take your
foot off the accelerator pedal. Your vehicle will
maintain the set speed.
● To pass another vehicle, depress the accel-
erator pedal. When you release the pedal,
the vehicle will return to the previously set
speed.
● The vehicle may not maintain the set speed
on winding or hilly roads. If this happens,
drive without the cruise control.
To cancel the preset speed, follow any of these
methods:
a) Push the CANCEL button. The SET indica- tor will go out.
b) Tap the brake pedal. The SET indicator will go out.

Each time the DISTANCE switchAis pushed,
the set distance will change to long, middle,
short and back to long again in that sequence. ●
The distance to the vehicle ahead will
change according to the vehicle speed. The
higher the vehicle speed, the longer the
distance. ●
If the engine is stopped, the set distance
becomes “long”. (Each time the engine is
started, the initial setting becomes “long”.)
Approach warning
If your vehicle comes closer to the vehicle
ahead due to rapid deceleration of that vehicle
or if another vehicle cuts in, the system warns
the driver with the chime and ICC system dis-
play. Decelerate by depressing the brake pedal
to maintain a safe vehicle distance if:
●The chime sounds.
● The vehicle ahead detection and set dis-
tance indicator blink.
The warning chime may not sound in some
cases when there is a short distance between
vehicles. Some examples are:
● When the vehicles are traveling at the same
speed and the distance between vehicles is
not changing
● When the vehicle ahead is traveling faster
and the distance between vehicles is in-
creasing
● When a vehicle cuts in near your vehicle

PREVIEW FUNCTION (for Intelligent
Cruise Control system equipped
models)
The ICC system with the preview function iden-
tifies the need to apply emergency braking by
sensing the vehicle ahead in the same lane and
the distance to the vehicle ahead and relative
speed from it, it applies the brake pre-pressure
before the driver depresses the brake pedal and
helps improve brake response by reducing
pedal free play.
For more details, see “BRAKE ASSIST” later in
this section.
CAUTION
During the first 1,200 miles (2,000 km), follow
these recommendations to obtain maximum
engine performance and ensure the future reli-
ability and economy of your new vehicle.
Failure to follow these recommendations may
result in shortened engine life and reduced en-
gine performance.
● Avoid driving for long periods at constant
speed, either fast or slow. Do not run the
engine over 4,000 rpm.
● Do not accelerate at full throttle in any gear.
● Avoid quick starts.
● Avoid hard braking as much as possible.

BREAK-IN SCHEDULE
Starting and driving5-43

●Accelerate slowly and smoothly. Maintain
cruising speeds with a constant accelerator
position.
● Drive at moderate speeds on the highway.
● Avoid unnecessary stopping and braking.
Keep a safe distance behind other vehicles.
● Select a gear range suitable to road condi-
tions.
● Avoid unnecessary prolonged engine idling.
● Keep your engine tuned up.
● Follow the recommended periodic mainte-
nance schedule.
● Keep the tires inflated at the correct pres-
sure. Improper tire pressure will increase
wear and waste fuel.
● Make sure the front wheels are properly
aligned. Improper alignment will cause pre-
mature tire wear and lower fuel economy.
● Climate control operation lowers fuel
economy. Use the air conditioner only when
necessary.
● When cruising at highway speeds, it is more
economical to use the air conditioner and
leave the windows closed to reduce drag. The AWD warning light is located in the meter.
The AWD warning light comes on when the
ignition switch is pushed to the ON position. It
turns off soon after the engine is started. If any malfunction occurs in the AWD system
while the engine is running, the warning light
will come on.
The warning light may blink rapidly (about twice
per second) while trying to free a stuck vehicle
due to high power train oil temperature. The
driving mode may change to two-wheel drive. If
the warning light blinks rapidly during opera-
tion, stop the vehicle with the engine idling in a
safe place immediately. Then if the light goes
off after a while, you can continue driving.
A large difference between the diameters of
front and rear wheels will make the warning
light blink slowly (about once per two seconds).
Pull off the road in a safe area, and idle the
engine. Check that all tire sizes are the same,
tire pressure is correct and tires are not worn.
If the warning light is blinking after the above
operation, have your vehicle checked by an
INFINITI retailer as soon as possible.

5-44Starting and driving

WARNING
●For AWD equipped vehicles, do not attempt
to raise two wheels off the ground and shift
the transmission to any drive or reverse po-
sition with the engine running. Doing so may
result in drivetrain damage or unexpected
vehicle movement which could result in seri-
ous vehicle damage or personal injury.
● Do not attempt to test an AWD equipped ve-
hicle on a 2-wheel dynamometer (such as
the dynamometers used by some states for
emissions testing) or similar equipment
even if the other two wheels are raised off
the ground. Make sure that you inform the
test facility personnel that your vehicle is
equipped with AWD before it is placed on a
dynamometer. Using the wrong test equip-
ment may result in drivetrain damage or un-
expected vehicle movement which could re-
sult in serious vehicle damage or personal
injury.
CAUTION
●Do not operate the engine on a free roller
when any of the wheels are raised.
● If the warning light comes on while driving
there may be a malfunction in the AWD sys-
tem. Reduce the vehicle speed and have your
vehicle checked by an INFINITI retailer as
soon as possible.
● If the warning light remains on after the
above operation, have your vehicle checked
by an INFINITI retailer as soon as possible.
● The power train may be damaged if you con-
tinue driving with the warning light blinking.

WARNING
●Do not stop or park the vehicle over flam-
mable materials such as dry grass, waste
paper or rags. They may ignite and cause a
fire.
● Never leave the engine running while the
vehicle is unattended.
● Do not leave children unattended inside the
vehicle. They could unknowingly activate
switches or controls. Unattended children
could become involved in serious accidents. ●
Safe parking procedures require that both
the parking brake be applied and the trans-
mission placed into P (Park) for Automatic
Transmission (AT) model or in an appropri-
ate gear for Manual Transmission (MT)
model. Failure to do so could cause the ve-
hicle to move unexpectedly or roll away and
result in an accident.
● Make sure the automatic transmission se-
lector lever has been pushed as far forward
as it can go and cannot be moved without
depressing the foot brake pedal.
1. Firmly apply the parking brake.
2. Automatic transmission models:
Move the selector lever to the P (Park)
position.
Manual transmission models:
Place the shift lever in the R (Reverse) gear.
When parking on an uphill grade, place the
shift lever in the 1st gear.
3. To help prevent the vehicle from rolling
into the street when parked on a sloping
drive way, it is a good practice to turn the
wheels as illustrated.
●HEADED DOWNHILL WITH CURB:1
Turn the wheels into the curb and move the
vehicle forward until the curb side wheel
gently touches the curb.
● HEADED UPHILL WITH CURB:
2
Turn the wheels away from the curb and
move the vehicle back until the curb side
wheel gently touches the curb.
● HEADED UPHILL OR DOWNHILL, NO CURB:
3
Turn the wheels toward the side of the road
so the vehicle will move away from the
center of the road if it moves.
4. Push the ignition switch to the OFF posi-
tion.

SONAR SYSTEM OFF SWITCH
The sonar system OFF switch on the instrument
panel allows the driver to turn the sonar system
on and off. To turn the sonar system on and off,
the ignition switch must be in the “ON” posi-
tion. The indicator light
1on the switch will
illuminate when the system is turned off. If the
indicator light flashes when the sonar system is
not turned off, it may indicate a malfunction in
the sonar system.
WARNING
If the engine is not running or is turned off while
driving, the power assist for the steering will
not work. Steering will be harder to operate.
The power assisted steering uses a hydraulic
pump, driven by the engine, to assist steering.
If the engine stops or the drive belt breaks, you
will still have control of the vehicle. However,
much greater steering effort is needed, espe-
cially in sharp turns and at low speeds.
BRAKING PRECAUTIONS
The brake system has two separate hydraulic
circuits. If one circuit malfunctions, you will still
have braking at two wheels.
Vacuum assisted brakes
The brake booster aids braking by using engine
vacuum. If the engine stops, you can stop the
vehicle by depressing the brake pedal. How-
ever, greater foot pressure on the brake pedal
will be required to stop the vehicle and the
stopping distance will be longer.
When the brake pedal is depressed slowly and
firmly, you may hear a clicking noise and feel a
slight pulsation. This is normal and indicates
that the Brake Assist System is operating.
Wet brakes
When the vehicle is washed or driven through
water, the brakes may get wet. As a result, your
braking distance will be longer and the vehicle
may pull to one side during braking.
To dry brakes, drive the vehicle at a safe speed
while lightly tapping the brake pedal to heat-up
the brakes. Do this until the brakes return to
normal. Avoid driving the vehicle at high speeds
until the brakes function correctly.
